I don’t know what professional astronomers will say about it but I think we are not going to see Earth and rest of solar system unless with powerful telescopes that can filter Oort Cloud that may block the view.
We will be able to see the solar system, and we can see through the Oort cloud. We do it all the time, from Earth. How do you think astronomers take pictures of stars light years away?
The Oort cloud is not as dense as you may think.
Out side of the solar system, we might now be able to see the inner planets, as they are too small and too close to the bright glare of the sun, but we will see the sun, and the outer planets (Jupiter, Saturn, Uranus, Neptune)
